ISIMIP3b ocean input data

The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.<br>The ISIMIP3b part of the third simulation round is dedicated to a quantification of climate-related risks at different levels of global warming and socio-economic change. ISIMIP3b group I simulations are based on historical climate change as simulated in CMIP6 combined with observed historical socio-economic forcing. ISIMIP3b group II simulations are based on climate change according to the CMIP6 future projections combined with socio-economic forcings fixed at 2015 levels. ISIMIP3b group III simulations additionally account for future changes in socio-economic forcing.<br>This dataset contains ocean climate input data for ISIMIP3b Marine Ecosystems and Fishery sector on a 1x1° grid. Data originates from CMIP6 archives and was remapped to a common regular global grid. It includes data from these global climate models which delivered data from a bio-geochemical submodule: GFDL-ESM4, UKESM1-0-LL, MPI-ESM1-2-HR and IPSL-CM6A-LR. For GFDL-ESM4 we fall back on the already remapped 1x1° data provided in ESGF while for the other 3 models we did the remapping on our own. In addition, MPI-ESM1-2-HR is also available on a half-degree grid. As requested by the modeling community, vertically integrated as well as ocean bottom and surface values for some variables were derived from the remapped data. The time series cover the period 1601-2100 for the piControl experiments, 1850-2014 for historical and 2015-2100 for the future experiments ssp126, ssp370 and ssp585, respectively.<br>Version 1.1 of this dataset fixes the direction of the latitude index in the GFDL-ESM4 files.

跨部门影响模型比对项目（Inter-Sectoral Impact Model Intercomparison Project，ISIMIP）提供了一套框架，用于整合跨部门、跨尺度的标准化气候影响数据集。同时，该项目也为通过标准化情景分析跨部门气候变化影响的相互作用提供了独特契机。
第三模拟轮次中的ISIMIP3b部分，旨在量化不同全球变暖水平与社会经济变化情境下的气候相关风险。ISIMIP3b第一组模拟以耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）模拟的历史气候变化，结合观测得到的历史社会经济强迫数据为基础。ISIMIP3b第二组模拟以CMIP6给出的未来气候变化预估为基础，同时将社会经济强迫固定在2015年水平。ISIMIP3b第三组模拟则额外考虑了社会经济强迫的未来变化。
本数据集包含ISIMIP3b海洋生态系统与渔业部门所需的1°×1°网格海洋气候输入数据。数据源自CMIP6档案库，并被重映射至统一的常规全球网格。数据集涵盖了以下具备生物地球化学子模块数据输出的全球气候模型的数据：GFDL-ESM4、UKESM1-0-LL、MPI-ESM1-2-HR以及IPSL-CM6A-LR。对于GFDL-ESM4模型，我们采用地球系统网格联合会（Earth System Grid Federation，ESGF）已提供的重映射1°×1°数据；其余三款模型的重映射工作则由我们自主完成。此外，MPI-ESM1-2-HR模型还提供半度网格的数据。按照建模社区的要求，我们从重映射后的数据中提取了部分变量的垂直积分值、洋底值以及表层值。时间序列的覆盖时段如下：piControl（理想气候控制试验）为1601-2100年，历史试验为1850-2014年，SSP126、SSP370与SSP585未来试验则分别为2015-2100年。
本数据集的1.1版本修正了GFDL-ESM4文件中纬度索引的方向。
